Review all SAFETY information in Section A.
This manual will alert personnel to known proce­
dures which require special attention, to those
which could damage equipment, and to those
which could be dangerous to personnel. However,
this manual cannot possibly anticipate and provide
detailed precautions for every situation that might
occur during maintenance of the unit. Therefore, it
is the responsibility of the owner/maintenance per­
sonnel to ensure that only safe, established main­
tenance procedures are used, and that any proce­
dures not addressed in this manual are performed
only after establishing that neither personal safety
nor pump integrity are compromised by such prac­
tices.
Death or serious personal injury and
damage to the pump or components
can occur if proper lifting procedures
are not observed. Make certain that
hoists, chains, slings or cables are in
good working condition and of suffi­
cient capacity and that they are posi­
tioned so that loads will be balanced
and the pump or components will not be
damaged when lifting. Do not attempt to
lift this pump by the motor or control
cables, or the piping. Attach proper lift­
ing equipment to the lifting bail fitted on
the pump. Lift the pump or component
only as high as necessary and keep per­
sonnel away from suspended objects.
If the pump is used to handle liquids
which may cause illness or disease
through direct exposure, take neces­
sary precautions during maintenance
and repair to prevent personal contam­
ination.
Select a suitable location, preferably indoors, to
perform required maintenance. All work must be
performed by qualified personnel.
Check the chart in TROUBLESHOOTING, Section
D of this manual, to determine the nature of the
pump problem. If the problem is mechanical in na­
ture, such as worn pump parts, seal replacement,
lubrication, etc., refer to the following instructions.
If the problem is electrical, maintenance may be
performed only by a Gorman‐Rupp authorized re­
pair facility, or the factory. Otherwise, the pump
warranty will be negated, and damage to the
pump, and injury or death to personnel can result.
Contact the factory for the authorized repair facility
closest to you.
The electrical power used to operate
this pump is high enough to cause inju­
ry or death. Make certain that the control
handle on the control box is in the off po­
sition and locked out, or that the power
supply to the control box has been
otherwise cut off and locked out, before
attempting to open or service the pump
assembly. Tag electrical circuits to pre­
vent accidental start‐up.
Carefully inspect any O‐rings before removal and
cleaning to determine if a proper seal and com­
pression existed prior to disassembly. If sealing
was faulty or questionable, the cause must be de­
termined and corrected before reassembly. All O‐
rings must be replaced if disturbed.

Preparing Pump for Disassembly
Use the hoisting bail to remove the pump from the
wet well or sump, and move it to a suitable location
for disassembly.
Do not attempt to lift the pump by the
motor power cable or the piping. Attach
